SPECIFICATION forming part of Letters Patent No. 756,505, dated April 5,1904.

Application led August 22, 1902.

T0 all whom it may concern:

Be it known that I, HENRYF. KELLEMEN, of Utica, in the county of Oneidaand State of New York, have invented certain new and useful Improvementsin Pliers; and I do hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings,and to the letters and figuresofreference marked thereon, which form part of this specification.

The object of my invention is to provide a pliers that is strong inconstruction, cheaply made, and in which a tempered cutting edge may bereadily provided without tempering or unnecessarily heating andtempering the whole tool.

In the drawings, Figure 1 shows in side elevation the tool with portionsof the handle broken ofi' to reduce the size of the iigure. Fig. 2 showsa section of same, taken on line A B of Fig. 1. Fig. 3 shows a sectiontaken on line C D of Fig. 1. Fig. 3 shows a section corresponding with OD of a modiiied form of construction. Fig. 4 shows the reverse side fromFig. 1 and also the same side of a modified form of construction. Fig. 5shows asection taken on line with O D' of Fig. 4 of the modied form ofconstruction mentioned. Figs. 6, 7, and 8 show various other modifiedforms of construction. Fig. 9 shows a section on line G H of Fig. 7.Fig. 10 shows a section on line E F of Fig. 7. Fig. 11 shows a sectionon line I K of Fig. 7.

Referring to the reference letters andiigures in a more particulardescription, 1 and 2 indicate the two main parts of the pliers, whichconsist of the handle portions 1a and 2, respectively, and the jawportions 1b and 2b, respectively. These two parts are halved or recessedtogether, as shown in Fig. 1, at the joint Aor crossing-point, which maybe without a pivot, as shown in Fig. 3, or with a pivot c, as shown inFig. 3a. When not provided with a pivot, each part is made rounded atthe joint and provided with a correspondingly-rounded recess, which whenthe two Serial No. 120,624. (No model.)

parts are placed together forms the joint. As shown in Fig. 1, each partis provided with a removable and retaining strengtheningpiece 4, whichspans the cut-out or recess of its part at the joint and is attached atits ends by screws 5 6 or other means to the handle and jaw parts,respectively. The parts 4 are 55 preferably recessed or inlet into thesides of the pliers, so as to lie' iiush with the general surface, orthey may be applied outside of the general lines of the plier jaws orparts. The jaws are preferably provided with recesses 7 8, which makeprovision for a wirecutter, and the wire-cutter is formed in theconstruction as shown in Fig. l as to one side at least, with a cuttingedge e formed on the piece 4. The piece 4 may be hardened 65 andtempered throughout its length or locally to provide said suitablecutting edge. The piece 4 when applied either singly on one side only ofthe pliers, as indicated at Fig. 3, or on both sides, as indicated inFigs. 2 70 and 3, serves to retain the parts of the pliers together atthe joint against lateral or sidewise displacement and, in fact, forms,essentially, what is known as a box-joint pliers. In` Fig. 3 theconstruction is shown with the 75 strengthening-piece 4 applied to oneside on one part of the pliers only and a rivet c employed in the joint.The rivet c may be employed in the other construction described ordispensed with in the one shown in Fig. 3a.

In the construction shown in Figs. 4 and 5 one of the plier parts, as 2,is recessedv or cut down at the joint thinner than the other part,

1', and when the piece 4, similar to 4, before described, is applied andsecured a box-joint pliers is formed which has the advantage of beingcapable of being taken apart and has the cutting edge e' formed on thepart 4.

The construction shown in Fig. 6 differs from that shown in Figs. 4 and5 in that an in- 90 let-piece 6 is provided,which provides the cuttingedge e, so that with the supplied pieces 4 and 6 the cutting edges foreach jaw are provided in separately-tempered pieces from the main partsof the pliers. The parts 6, as well as the parts 4 and 4, are preferablybeveled in opposite directions at each end, so'that they wedge in therecesses in the plier parts and will better withstand pressure on thecuttingjaws.

In the construction shown in Figs. 7, 9, 10, and l1 a pair of plates lOand Il are provided upon the same side of the pliers. The plate l() issimilar to plate 4, heretofore described, secured at its respective endsto the jaw and handle portions, respectively, and spanning the cut-outin the plier part to which it is attached and providing the cuttingedge, as heretofore described. The piece 11 is similar to 10 on theother plier part and serves more particularly to provide the cutting-jawe'" for its particular jaw. In this construction the plier parts l and2, respectively, are halved or recessed together, as heretoforedescribed, and, as shown in Fig. 10, are provided with a pivot p. Thispivot, however, may be dispensed with.

Fig. 8 shows a construction similar to Fig. 7, except that the jaw-piecel1 is not attached to the handle portion of this plier part,and therivet p of this construction is allowed to pass entirely through themain parts and cutting parts of this construction.

. What I claim as new, and desire to secure by Letters Patent, is-

l. The combination in a pliers of the parts each constituting a jaw andhandle cut out or halved together at the joint and a strengtheningjoint-piece spanning the cutout in the part and secured at each side ofsaid cut-out @sesos vto the jaw and handlerespectively, substantially as'set forth.

2. The combination in a pliers of the two parts each consisting of a jawand handle cut out or halved together at the joint, and a jointpiecespanning the cut-out in the part and secured at each side thereof to thejaw and handle parts, respectively, and providing a cutting edge formedon the jaw end of the jointpiece, substantially as set forth.

3. The combination in a pliers of the two crossing parts each consistingof a jaw and handle cut out or halved together at the joint and aremovable joint-piece spanning the cutout and secured at each sidethereof to the jaw and handle, respectively, and serving to secure theparts together against sidewise displacement, substantially as setforth.V

4. rJhe combination in a pliers of the two parts crossing and halvedtogether at the joint, one of said parts being recessed or cut out to agreater extent than the other, and a supplemental strengthening-piecespanning the recess or cut-out of the part which is more cut out orrecessed and secured at each end and inclosing the other part at thejoint, substantially as set forth.

' In witness whereof I have affixed my signature, in presence of twowitnesses,this 20th day of August, 1902.
